sAsH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 278,042, dated May 22, 1883.

Application filed December 23, 1882.

To alt whom it 'may concern Be it known that I, DANIEL L. PHIPPs, ot' Millington, in the county of Tuscola. and State of Michigan, have invented new and useful Improvements in Devices for Hanging Window-Sash, and I hereby declare that the following is a. full, clear, and vexact description Figure l is an elevation of a' Window, with a portion of' the frame broken away. Fig. 2 is au elevation of the edge of the sash.

In the accompanying drawings, A represents thesash ot' a windo\v,and B the jamb or frame. In the face of the jamb I form a recess to receive the recessed plate C, iu which is pivotally secured, in any proper and convenient (Model.)

manner, the worm D, the peripheryvof which projects slightly beyond the face of the jamb. In the edge ofthe sash-frame I insert the racklbar E, the face ot the teeth ot' which are flush with the edge of the sash, and are upon the same pitch or inclination as the pitch of the worm D, with which the said rack-bar engages when the sash is in place.

In practice it will be found that a window provided with this device can be easily raised or lowered, as may be desired, and with a worm and rack-bar will form a lock which will hold the sash in the position in which it is left.

In, fitting this device to the window the rack should extend the whole length of the sash, while the Worm for the lower sash should be placed near the top ot' such sash and the one for the upper sash near its lower end.

What I claim as my invention is- Iu combination with awiudow-sash and the frame thereof', the worm D and rack E, when constructed, arranged, and operating substantially as and for the purposes set forth.
